RESISTANCE BOXES (PLUG TYPE)

USE: TO CALCULATE OR FIND OUT THE RESISTANCE OF A COIL and A simple use of the resistance box is to wire it to a battery via a galvanometer and two way key to measure an unknown resistance as in figure 3. Read the galvanometer deflection with the unknown resistance in circuit then change over and adjust the resistance box until the same deflection is obtained. Read off the resistance in circuit and there you have it. Other simple uses include adjusting relay timing, balancing duplex or quad telephony and in laboratory work.
